Towards Robust and Low Latency Security Framework for IEEE 802.11 Wireless Networks

Abstract

The vulnerability in wireless networks require additional security, integrity, and authentication. The outdated "Counter Mode Cipher Block Chaining Message Authentication Code Protocol" (CCMP) has lately taken the place of the flawed "Wired Equivalent Privacy" (WEP) protocol for authenticating IEEE 802.11 wireless local area networks (WLANs). IEEE 802.11s, a draught standard for wireless mesh networks, also recommended using CCMP (WMNs). Due to CCMP's two-pass operation, multi-hop wireless networks like WMN have a considerable latency problem. An increase in latency results in a decrease in service quality for real-time multimedia applications sensitive to delays. In addition to highlighting the CCMP's vulnerability to pre-computation time-memory trade-off (TMTO) attacks, this paper recommends improving WLAN packet security by implementing a per-packet security mechanism. Furthermore, suggested is a fresh, dependable, low-latency foundation for WMN. The security framework's architecture employs a piggyback challenge-response mechanism to ensure data secrecy and data integrity ۔The use of a secret nonce, a new encryption key for each packet, and packet-level authentication are all features of the Piggyback challenge-response protocol. By authenticating every packet, unauthorized access can be swiftly prevented.
